Arm support in Docker images

[derschatta]

I was able to build and push images up following these instructions: https://medium.com/geekculture/docker-build-with-mac-m1-d668c802ab96

I've built some test images:

• totara/docker-dev-apache:multiarch
• totara/docker-dev-nginx:multiarch
• totara/docker-dev-php73:multiarch
• totara/docker-dev-php73-cron:multiarch
• totara/docker-dev-php73-debug:multiarch
• totara/docker-dev-php74:multiarch
• totara/docker-dev-php74-cron:multiarch
• totara/docker-dev-php74-debug:multiarch
• totara/docker-dev-php80:multiarch
• totara/docker-dev-php80-cron:multiarch
• totara/docker-dev-php80-debug:multiarch
• totara/docker-dev-php81:multiarch
• totara/docker-dev-php81-cron:multiarch
• totara/docker-dev-php81-debug:multiarch

These need to be tested on a Mac with M1 or M2 chip. If they work I can see how we can create these images automatically.

The easiest way would be to create an arm.yml file under /custom/:

version: "3.7"
services:

  apache:
    image: totara/docker-dev-apache:multiarch

  nginx:
    image: totara/docker-dev-nginx:multiarch

  php-7.3:
    image: totara/docker-dev-php73:multiarch

  php-7.3-cron:
    image: totara/docker-dev-php73-cron:multiarch

  php-7.3-debug:
    image: totara/docker-dev-php73-debug:multiarch

  php-7.4:
    image: totara/docker-dev-php74:multiarch

  php-7.4-cron:
    image: totara/docker-dev-php74-cron:multiarch

  php-7.4-debug:
    image: totara/docker-dev-php74-debug:multiarch
    
  php-8.0:
    image: totara/docker-dev-php80:multiarch

  php-8.0-cron:
    image: totara/docker-dev-php80-cron:multiarch

  php-8.0-debug:
    image: totara/docker-dev-php80-debug:multiarch
    
  php-8.1:
    image: totara/docker-dev-php81:multiarch

  php-8.1-cron:
    image: totara/docker-dev-php81-cron:multiarch

  php-8.1-debug:
    image: totara/docker-dev-php81-debug:multiarch

and tup the php container. The postgres image, e.g. pgsql14, should already have multiarch support.

@benfes @Kunleodusan Could you try this out for me and see if the images work and whether there's any difference in performance?

Also noting that the Mssql server 2017 and 2019 is not available for ARM so we'd have to stick with the AMD64 ones for now. Will check out the 2022 version though. We do not yet support it but it would be interesting to see if Totara runs on it.

Created some docs: https://github.com/totara/totara-docker-dev/wiki/Apple-Silicon-support

@jonnybarnes if you want to give this a try go for it and let us know if it works and whether there's an improvement.

patch merged into develop. Can already be used by following the instructions on the wiki page. Closing.

This works! Thanks

I don’t have hard numbers, but it feels quicker with dev mode tuned off in the config.php, it feels just as slow with dev mode turned on though 🐌
